“I have a Ruger Security-380. I like it, but I is very picky about ammo brands. There are several brands that won't feed in my Ruger properly. I have had no problems with the Winchester flat-nose rounds. They feed reliably and have the added benefit of leaving nice round holes in paper targets.”
“I like using the Winchester Flat Nose rounds in my Ruger Security-380 as it leaves nice round holes in paper rather than ripping the paper as round nose rounds do. This ammo also feeds well in my Ruger where as, some other rounds frequently jam.”
